Swedish police are investigating this morning after finding drugs and a stun gun on board Justin Bieber’s tour bus last night. The raid happened last night during Bieber’s concert in Stockholm.

A police spokesman told the AP that police raided the bus after they smelled marijuana coming from the bus. No one was arrested as the bus was empty at the time. The spokesman declined to identify what drug was found, but from context clues we can probably assume it some type of drug that smells like marijuana. Whip-its maybe?

Police say they have no suspects, and no known terror cells have taken credit for framing the Canadian pop star.

In January of this year, TMZ released photos that appear to show Bieber himself smoking what the site claimed was marijuana in a California hotel room. He addressed the controversy while hosting Saturday Night Live in February, saying, in character as someone else, “I also heard he got busted for smoking weed and he’s really sorry about it and people make mistakes and he’s never gonna do it again.”
